Besides genuine skin and clothes, it is called that building is third skin for us. That means the skin of buildings is the most important factor for our man-made environment. The issues in designing the building envelope include the insulation, infiltration, ventilation and bridging in windows. Getting light into the space safely and providing views to outdoor, additionally, are key things with the building envelope design. A deep-rooted preference for full view is still alive with large area of glass. Balcony expansion is legalized in apartment houses, which causes lots of environmental problems. Without balcony space, the adjacent space to unshaded window is exposed to the direct sun. A window can have many layers and the inner space can be utilized with an automatic blind system. Recently, the refurbished version of a double-glazed window system has been developed for the purpose of minimizing energy loss occurred around windows. For the better daylight control with equipped blind system, a set of adjustment technique of blind slats was tested in a mock-up building and recommended the detail operation. Not surprisingly, the optimized blind system can be oriented to enhance the uniformity in light distribution and direct glare from the sky as well..

The public has grown more anxious towards domestic earthquakes that have been taking place since 2000, and regulations on seismic design has been strengthened. Out of 4,605 Air Force installations that require the application of seismic design, 2,982 remain unapplied. By taking budget issues and the time spent to implement seismic retrofit into account, this paper aims to list up seismic reinforcement priorities for airmen dormitories where they can potentially be most vulnerable to earthquakes. The priorities are extracted based on Data Envelope Analysis(DEA). To apply DEA, two sets of variables are set: seismic reinforcement costs as input variable: age of building, number of residents, and seismic load as output variables. At the end, suggestions are made for developing seismic reinforcement plans that can be applied to all Air Force installations.

The application of photovoltaics into building as integrated building components has been paid more attention worldwide. Photovoltaics or solar electric modules are solid state devices, directly converting solar radiation into electricity; the process does not require fuel and any moving parts, and produce no pollutants. And the prefab building method is very effective because the pre- manufactured building components is simply assembled to making up buildings in the construction fields especially the sandwich panel. Architecture considerations for the integration of PV module to building envelope such as building structure, construction type, safety, regulation, maintenance etc. have been carefully refelected from the early stage of BIPV module design. Trial product of BIPV module are manufactured and sample construction details for demonstration building are purposed. Therefore, this paper intends to advanced its practical use by proposing how to get integrated PV system which can be applied to prefab building material, and how to apply it.

본 연구의 목적은 면진건물의 설계를 수행하는데 있어, 면진건물의 주기, 수평 변위량 등과 같은 면진장치의 성능을 결정하기 위한 중요 요소들을 손쉽게 산정할 수 있는 포락해석용 도표를 산정하는데 있다. 이를 위하여 가속도로 표현되는 설계지진의 위험도 대신, 에너지와 관계된 $V_E$ 스펙트럼을 아울러 산정한다. UBC 97의 지진응답계수를 적용한 경계주기 $T_G$ 및 최대속도 응답 $V_0$를 지반조건별로 제안하였으며, 이를 근간으로 한 스펙트럼 작성법을 제안하였다. 제안된 $V_E$ 스펙트럼을 근거로 지반조건별 포락해석용 도표를 작성하였다.

세계 각국에서는 환경오염이나 에너지절감을 위한 방안으로 건축물에 대한 가이드라인과 제도적 지원이 활성화되고 있다. 우리나라에서도 2013.09.01. 개정된 "건축물의 에너지절약 설계기준"에 따라 기준들이 마련되고 신축 건축물에 대한 제로에너지빌딩화가 권장사항에서 의무화과정으로 가고 있다. 그럼에도 불구하고 소형건물에 대한 정부의 구속력은 미비한 실정이다. 이에 최근에 시공한 오피스건물(외단열기법 적용)에 대해 에너지 절감효과를 분석하였고 추가적으로 에너지 절감을 위한 이중외피기법을 제안하였다.

Recently, curtainwall is built according to expand residential-commercial complex and high-raised buildings in residential buildings. It is that curtainwall has advantage to provide for the building occupants a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building. These buildings also make a result increasing the amount used energy in domestic residence. Therefore, Aims of this study is to suggest advanced design through analysis of daylight, energy and envelope elements in GBCC and glazing simulation depended on case studies.

Double skin façade is known that several features affected the building energy and daylighting performance. That is why the envelope is able to consist of all architectural materials such as glass, aluminum, wood and insulation for vision of residents and workers in buildings. Its specifications is very diverse according to the building designers and building owners. In recent times, visual environment became a major focus and resulted in the development of cutting edge engineering of diverse glazing systems and shading devices by growing interests of friendly environment. Thus this research has evaluated the fluctuations of interior lighting and atmospheric conditions based on double skin facade systems. Especially in terms of daylighting environment as dependent on solar variations, this research provides quantitative analysis of interior lighting conditions and how it affects the living conditions as well as improve the design of interior spaces.

The purpose of this study was to consider the energy generation of the building as well as the energy demand of the building in terms of zero energy building design. The reason why the zero energy building viewpoint should be discussed is that direction of the building, heat transfer rate of the building, and the S/V ratio of the building are variables related to energy demand and solar panels installed on the building roof and building envelope are variables related to energy generation. This study proceeded as follows; Firstly, the simulation model of large office and elementary school has the same mutual volume and total floor area, and the each floor area and number of floors are adjusted so that the S/V ratio is different. To the next, the energy demand and energy generation of the simulation model were derived based on the meteorological data of Seoul, Daejeon, Busan. Finally, energy demand, energy generation, and final energy demand were compared with heat transfer rate, S/V ratio, building type, region, and orientation. The results of this study is that consideration of solar power generation in terms of energy generation should be taken into consideration at the same time in consideration of the heat transfer rate, the shape, the region and the direction of the zero energy building design.

Sustainable design is getting to be controversial issue in all industries over the world particularly, in architecture as the amount of energy usage in architecture occupies 40%. Therefore, it is essential to make the standard for the sustainable design. In order to construct the sustainable design, firstly it should be considered that sustainable design elements based on natural resources to increase building energy efficiency is established and classified. The method of sustainable design divides into passive design and active design. Passive design method should be examined with active one simultaneously for more efficient usage of energy. Next, the study is followed how the sustainable design elements is adopted in buildings through the comparison of cases study of domestic and oversea. The result of case study shows similar adoption of sustainable design elements between oversea and domestic. However, the difference is shown in the building orientation and shape and the window size and position in Solar energy as well as high performance structure in Heat energy. These elements are the most significant elements in order to reduce energy load. In oversea, sustainable design is generated by architects, a client, and consultants based on the close cooperation in the beginning of early design phase before deciding building shape and envelope while in the domestic field adoption for sustainable design is conducted after deciding building shape and material. In order to design sustainable architecture more study is necessary in early stage for Zero Carbon and reducing building energy load through relation with specialists, a client and architects.
